This fully illustrated book traces the history of underwater travel, from the earliest attempts to travel beneath the waves to the future possibility of unmanned craft permanently roaming the seas.

Beginning with a detailed history, this book follows the development of the submarine from the Cold War onwards, with special topics including life aboard the Dreadnought, the ballistic boomers, the tragedy of the Kursk and deep sea survival teams.

Describes more than 270 submarines, with information on such topics as their history, number of submarines built, when they were completed, their displacement, their deployment, propulsion, and weapons.

Presents information about submarines, from providing a room-by-room tour of a typical vessel to analyzing the history of submarines during wars and on maneuvers.

The period covered by this book was one of radical change for the U.S. Navy. When the modern navy first considered buying a submarine in 1887, it was a coast defense force confined to the Western Hemisphere. The United States became a world power just as its new submarines offered a way of defending its most distant possession, the Philippines, without tying down an expensive fleet. World War I found U.S. submarines in an unexpected role, countering German U-boats in British waters. Then the situation changed again with unexpected speed.

The submarine was undoubtedly the most potent purely naval weapon of the twentieth century. In two world wars, enemy underwater campaigns were very nearly successful in thwarting Allied hopes of victory - indeed, annihilation of Japanese shipping by US Navy submarines is an indicator of what might have been. That the submarine was usually defeated is a hugely important story in naval history, yet this is the first book to treat the subject as a whole in a readable and accessible manner. It concerns individual heroism and devotion to duty, but also ingenuity, technical advances and originality of tactical thought. What developed was an endless battle between forces above and below the surface, where a successful innovation by one side eventually produces a counter-measure by the other in a lethal struggle for supremacy. Development was not a straight line: wrong ideas and assumptions led to defeat and disaster.

World War 1 was a global military conflict. It began as a skirmish between Serbia and Austria-Hungary with the assassination of Arch Duke Ferdinand in June 1914 and was transformed into a European war when Germany declared war on Russia on August 1, 1914. The loss of life was unequalled, with some 8 million solders and more than 6 million civilians dying during four years of stagnant trench warfare and in failed attacks. It was the first time that many of the military technologies we now take for granted were seen, including aircraft, submarines and tanks. Yet, these were overshadowed by more established weapons such as machine guns, and artillery, the most lethal weapon of all. This visual encyclopedia looks at the key weapons used during the Great War. Each is listed chronologically within sections on the Army, Air Force and Navy. Each weapon features a brief history with a description on how it was used and key specifications, such as calibre, magazine, system, length, weight and muzzle velocity. The first section on Army Weapons features weapons used by the armies and infantry men, such as mortars, rifles and tanks. This is followed by Airforce Weapons and Airships, which includes bombers, fighter aircraft and Zeppelins. Finally Naval Weapons features the warships of Germany's Imperial Navy, the Royal Navy and the Allied powers' fleets, from the early battleships to more modern dreadnoughts and destroyers. From rifles, the main weapon used by British infantry men, to machine guns which needed four to six men to work them, and from tanks which were used for the first time during the battle of Somme to the new torpedo-boats whose main targets were the older battleships and more modern dreadnoughts, this is a detailed and fascinating guide to the military technologies developed during the First World War. Illustrated with more than 180 evocative contemporary photographs, the book will offer new insights for both general and specialist readers.
